This is a trend i have noticed that is popping up in many new horror flicks,
What the editors are doing is taking high violence scenes and color correcting (filtering) them to have a certain look that i feel works brilliantly, enhancing the realism to the whole visual effect.
Example is 'The hills have eyes', when ever theirs a full on fight scene heaps of blood etc, they make it look almost like a bleached filter look, only obviously a bit different.
It's like they skip frames to have it jolt a little and everything seems to move in a strange fast realistic way.
Now trying to write this look is of course impossible but I'm hoping that one of you movie buffs will trigger what effect I'm talking about and will know how it is, or have an idea to how you think they are doing this.
The hills have eyes is the only one that comes to mind at the moment, but I'll post more examples as they come back to the memory bank.
